BACKGROUND

Surgical simulations, such as computer-based, three-dimensional simulations of a surgical environment and/or surgical procedure for example, present an opportunity to advance the surgical arts. Surgical simulations have potential to benefit surgical training, planning, development, and the like. For example, surgical simulations may be used to train surgeons in new procedures and/or to improve the performance of procedures they already know. Surgical simulations may be used as a virtual “dress rehearsal” to help a surgeon prepare for an upcoming procedure. And surgical simulations may be used to experiment with unproven procedures and techniques.

However, surgical simulation platforms are complex systems that face many limitations in capabilities, scope, and applicability. For example, many platforms are technology “silos,” specifically programmed and tailored to address a particular learning objective or to simulate the operation of a singular piece of equipment, such as simulating the operation of a surgical robot. Limitations, such as these, may diminish a platform's effectiveness as a tool to advance the surgical arts. And such limitations may represent significant technological roadblocks to the integration of simulation-based applications into other aspects of the surgical process, such a pre-operative planning, intra-operative support, post-operative analysis, and the like.

Accordingly, innovation in surgical simulation technology, such as technical advancements that address surgical simulation capabilities, scope, and applicability for example, may accelerate further progress in the surgical arts.

DETAILED DESCRIPTION

Surgical simulation systems, devices, and methods may include aspects of integration with other medical equipment, data sources, processes, and institutions. Surgical simulation systems, devices, and methods may include aspects of integration with a computer-implemented interactive surgical system and/or with one or more elements of a computer-implemented interactive surgical system, for example.

Referring to FIG. 1, a computer-implemented interactive surgical system 100 may include one or more surgical systems 102 and a cloud-based system (e.g., the cloud 104 that may include a remote server 113 coupled to a storage device 105). Each surgical system 102 may include at least one surgical hub 106 in communication with the cloud 104 that may include a remote server 113.

One or more simulation devices 103, 111 may be in communication with and/or integrated as part of the computer-implemented interactive surgical system 100. For example, the simulation device 103 may be an element of the one or more surgical systems 102. For example, the simulation device 103 may be in communication with one or more surgical hubs 106. For example, the simulation device 111 may be in communication with the computer-implemented interactive surgical system 100 via the cloud 104.

In one example, as illustrated in FIG. 1, the surgical system 102 includes a visualization system 108, a robotic system 110, and a handheld intelligent surgical instrument 112, which are configured to communicate with one another and/or the hub 106. In some aspects, a surgical system 102 may include an M number of hubs 106, an N number of visualization systems 108, an O number of robotic systems 110, and a P number of handheld intelligent surgical instruments 112, where M, N, O, and P may be integers greater than or equal to one.

In various aspects, the visualization system 108 may include one or more imaging sensors, one or more image-processing units, one or more storage arrays, and one or more displays that are strategically arranged with respect to the sterile field, as illustrated in FIG. 2. In one aspect, the visualization system 108 may include an interface for HL7, PACS, and EMR. Various components of the visualization system 108 are described under the heading “Advanced Imaging Acquisition Module” in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety.

As illustrated in FIG. 2, a primary display 119 is positioned in the sterile field to be visible to an operator at the operating table 114. In addition, a visualization tower 111 is positioned outside the sterile field. The visualization tower 111 may include a first non-sterile display 107 and a second non-sterile display 109, which face away from each other. The visualization system 108, guided by the hub 106, is configured to utilize the displays 107, 109, and 119 to coordinate information flow to operators inside and outside the sterile field. For example, the hub 106 may cause the visualization system 108 to display a snapshot of a surgical site, as recorded by an imaging device 124, on a non-sterile display 107 or 109, while maintaining a live feed of the surgical site on the primary display 119. The snapshot on the non-sterile display 107 or 109 can permit a non-sterile operator to perform a diagnostic step relevant to the surgical procedure, for example.

In one aspect, the hub 106 may also be configured to route a diagnostic input or feedback entered by a non-sterile operator at the visualization tower 111 to the primary display 119 within the sterile field, where it can be viewed by a sterile operator at the operating table. In one example, the input can be in the form of a modification to the snapshot displayed on the non-sterile display 107 or 109, which can be routed to the primary display 119 by the hub 106.

Referring to FIG. 2, a surgical instrument 112 is being used in the surgical procedure as part of the surgical system 102. The hub 106 may also be configured to coordinate information flow to a display of the surgical instrument 112. For example, in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety. A diagnostic input or feedback entered by a non-sterile operator at the visualization tower 111 can be routed by the hub 106 to the surgical instrument display 115 within the sterile field, where it can be viewed by the operator of the surgical instrument 112. Example surgical instruments that are suitable for use with the surgical system 102 are described under the heading “Surgical Instrument Hardware” and in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety, for example.

FIG. 2 depicts an example of a surgical system 102 being used to perform a surgical procedure on a patient who is lying down on an operating table 114 in a surgical operating room 116. A robotic system 110 may be used in the surgical procedure as a part of the surgical system 102. The robotic system 110 may include a surgeon's console 118, a patient side cart 120 (surgical robot), and a surgical robotic hub 122. The patient side cart 120 can manipulate at least one removably coupled surgical tool 117 through a minimally invasive incision in the body of the patient while the surgeon views the surgical site through the surgeon's console 118. An image of the surgical site can be obtained by a medical imaging device 124, which can be manipulated by the patient side cart 120 to orient the imaging device 124. The robotic hub 122 can be used to process the images of the surgical site for subsequent display to the surgeon through the surgeon's console 118.

Other types of robotic systems can be readily adapted for use with the surgical system 102. Various examples of robotic systems and surgical tools that are suitable for use with the present disclosure are described in U.S. Patent Application Publication No. US 2019-0201137 A1 (U.S. patent application Ser. No. 16/209,407), titled METHOD OF ROBOTIC HUB COMMUNICATION, DETECTION, AND CONTROL, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety.

Various examples of cloud-based analytics that are performed by the cloud 104, and are suitable for use with the present disclosure, are described in U.S. Patent Application Publication No. US 2019-0206569 A1 (U.S. patent application Ser. No. 16/209,403), titled METHOD OF CLOUD BASED DATA ANALYTICS FOR USE WITH THE HUB, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety.

In various aspects, the imaging device 124 may include at least one image sensor and one or more optical components. Suitable image sensors may include, but are not limited to, Charge-Coupled Device (CCD) sensors and Complementary Metal-Oxide Semiconductor (CMOS) sensors.

The optical components of the imaging device 124 may include one or more illumination sources and/or one or more lenses. The one or more illumination sources may be directed to illuminate portions of the surgical field. The one or more image sensors may receive light reflected or refracted from the surgical field, including light reflected or refracted from tissue and/or surgical instruments.

The one or more illumination sources may be configured to radiate electromagnetic energy in the visible spectrum as well as the invisible spectrum. The visible spectrum, sometimes referred to as the optical spectrum or luminous spectrum, is that portion of the electromagnetic spectrum that is visible to (i.e., can be detected by) the human eye and may be referred to as visible light or simply light. A typical human eye will respond to wavelengths in air that are from about 380 nm to about 750 nm.

The invisible spectrum (e.g., the non-luminous spectrum) is that portion of the electromagnetic spectrum that lies below and above the visible spectrum (i.e., wavelengths below about 380 nm and above about 750 nm). The invisible spectrum is not detectable by the human eye. Wavelengths greater than about 750 nm are longer than the red visible spectrum, and they become invisible infrared (IR), microwave, and radio electromagnetic radiation. Wavelengths less than about 380 nm are shorter than the violet spectrum, and they become invisible ultraviolet, x-ray, and gamma ray electromagnetic radiation.

In various aspects, the imaging device 124 is configured for use in a minimally invasive procedure. Examples of imaging devices suitable for use with the present disclosure include, but not limited to, an arthroscope, angioscope, bronchoscope, choledochoscope, colonoscope, cytoscope, duodenoscope, enteroscope, esophagogastro-duodenoscope (gastroscope), endoscope, laryngoscope, nasopharyngo-neproscope, sigmoidoscope, thoracoscope, and ureteroscope.

The imaging device may employ multi-spectrum monitoring to discriminate topography and underlying structures. A multi-spectral image is one that captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, e.g., IR and ultraviolet. Spectral imaging can allow extraction of additional information the human eye fails to capture with its receptors for red, green, and blue. The use of multi-spectral imaging is described in greater detail under the heading “Advanced Imaging Acquisition Module” in U.S. Patent Application Publication No. US 2019-0200844 A1 (U.S. patent application Ser. No. 16/209,385), titled METHOD OF HUB COMMUNICATION, PROCESSING, STORAGE AND DISPLAY, filed Dec. 4, 2018, the disclosure of which is herein incorporated by reference in its entirety. Multi-spectrum monitoring can be a useful tool in relocating a surgical field after a surgical task is completed to perform one or more of the previously described tests on the treated tissue. It is axiomatic that strict sterilization of the operating room and surgical equipment is required during any surgery. The strict hygiene and sterilization conditions required in a “surgical theater,” i.e., an operating or treatment room, necessitate the highest possible sterility of all medical devices and equipment. Part of that sterilization process is the need to sterilize anything that comes in contact with the patient or penetrates the sterile field, including the imaging device 124 and its attachments and components. It will be appreciated that the sterile field may be considered a specified area, such as within a tray or on a sterile towel, that is considered free of microorganisms, or the sterile field may be considered an area, immediately around a patient, who has been prepared for a surgical procedure. The sterile field may include the scrubbed team members, who are properly attired, and all furniture and fixtures in the area.

Referring now to FIG. 3, a hub 106 is depicted in communication with a visualization system 108, a robotic system 110, and a handheld intelligent surgical instrument 112. The hub 106 includes a hub display 135, an imaging module 138, a generator module 140, a communication module 130, a processor module 132, a storage array 134, and an operating-room mapping module 133. In certain aspects, as illustrated in FIG. 3, the hub 106 further includes a smoke evacuation module 126 and/or a suction/irrigation module 128. During a surgical procedure, energy application to tissue, for sealing and/or cutting, is generally associated with smoke evacuation, suction of excess fluid, and/or irrigation of the tissue. Fluid, power, and/or data lines from different sources are often entangled during the surgical procedure. Valuable time can be lost addressing this issue during a surgical procedure. Detangling the lines may necessitate disconnecting the lines from their respective modules, which may require resetting the modules. The hub modular enclosure 136 offers a unified environment for managing the power, data, and fluid lines, which reduces the frequency of entanglement between such lines. Aspects of the present disclosure present a surgical hub for use in a surgical procedure that involves energy application to tissue at a surgical site. The surgical hub includes a hub enclosure and a combo generator module slidably receivable in a docking station of the hub enclosure. The docking station includes data and power contacts. The combo generator module includes two or more of an ultrasonic energy generator component, a bipolar RF energy generator component, and a monopolar RF energy generator component that are housed in a single unit. In one aspect, the combo generator module also includes a smoke evacuation component, at least one energy delivery cable for connecting the combo generator module to a surgical instrument, at least one smoke evacuation component configured to evacuate smoke, fluid, and/or particulates generated by the application of therapeutic energy to the tissue, and a fluid line extending from the remote surgical site to the smoke evacuation component. In one aspect, the fluid line is a first fluid line and a second fluid line extends from the remote surgical site to a suction and irrigation module slidably received in the hub enclosure. In one aspect, the hub enclosure comprises a fluid interface. Certain surgical procedures may require the application of more than one energy type to the tissue. One energy type may be more beneficial for cutting the tissue, while another different energy type may be more beneficial for sealing the tissue. For example, a bipolar generator can be used to seal the tissue while an ultrasonic generator can be used to cut the sealed tissue. Aspects of the present disclosure present a solution where a hub modular enclosure 136 is configured to accommodate different generators, and facilitate an interactive communication therebetween. One of the advantages of the hub modular enclosure 136 is enabling the quick removal and/or replacement of various modules. Aspects of the present disclosure present a modular surgical enclosure for use in a surgical procedure that involves energy application to tissue. The modular surgical enclosure includes a first energy-generator module, configured to generate a first energy for application to the tissue, and a first docking station comprising a first docking port that includes first data and power contacts, wherein the first energy-generator module is slidably movable into an electrical engagement with the power and data contacts and wherein the first energy-generator module is slidably movable out of the electrical engagement with the first power and data contacts. Further to the above, the modular surgical enclosure also includes a second energy-generator module con-figured to generate a second energy, different than the first energy, for application to the tissue, and a second docking station comprising a second docking port that includes second data and power contacts, wherein the second energy-generator module is slidably movable into an electrical engagement with the power and data contacts, and wherein the second energy-generator module is slidably movable out of the electrical engagement with the second power and data contacts. In addition, the modular surgical enclosure also includes a communication bus between the first docking port and the second docking port, configured to facilitate communication between the first energy-generator module and the second energy-generator module. Referring to FIG. 3, aspects of the present disclosure are presented for a hub modular enclosure 136 that allows the modular integration of a generator module 140, a smoke evacuation module 126, and a suction/irrigation module 128. The hub modular enclosure 136 further facilitates interactive communication between the modules 140, 126, 128. The generator module 140 can be a generator module with integrated monopolar, bipolar, and ultrasonic components supported in a single housing unit slidably insertable into the hub modular enclosure 136. The generator module 140 can be configured to connect to a monopolar device 142, a bipolar device 144, and an ultrasonic device 146. Alternatively, the generator module 140 may comprise a series of monopolar, bipolar, and/or ultrasonic generator modules that interact through the hub modular enclosure 136. The hub modular enclosure 136 can be configured to facilitate the insertion of multiple generators and interactive communication between the generators docked into the hub modular enclosure 136 so that the generators would act as a single generator.

FIG. 4 illustrates a surgical data network 201 comprising a modular communication hub 203 configured to connect modular devices located in one or more operating theaters of a healthcare facility, or any room in a healthcare facility specially equipped for surgical operations, to a cloud-based system (e.g., the cloud 204 that may include a remote server 213 coupled to a storage device 205). In one aspect, the modular communication hub 203 comprises a network hub 207 and/or a network switch 209 in communication with a network router. The modular communication hub 203 also can be coupled to a local computer system 210 to provide local computer processing and data manipulation. The surgical data network 201 may be configured as passive, intelligent, or switching. A passive surgical data network serves as a conduit for the data, enabling it to go from one device (or segment) to another and to the cloud computing resources. An intelligent surgical data network includes additional features to enable the traffic passing through the surgical data network to be monitored and to configure each port in the network hub 207 or network switch 209. An intelligent surgical data network may be referred to as a manageable hub or switch. A switching hub reads the destination address of each packet and then forwards the packet to the correct port.

Modular devices 1 a-1 n located in the operating theater may be coupled to the modular communication hub 203. The network hub 207 and/or the network switch 209 may be coupled to a network router 211 to connect the devices 1 a-1 n to the cloud 204 or the local computer system 210. Data associated with the devices 1 a-1 n may be transferred to cloud-based computers via the router for remote data processing and manipulation. Data associated with the devices 1 a-1 n may also be transferred to the local computer system 210 for local data processing and manipulation. Modular devices 2 a-2 m located in the same operating theater also may be coupled to a network switch 209. The network switch 209 may be coupled to the network hub 207 and/or the network router 211 to connect to the devices 2 a-2 m to the cloud 204. Data associated with the devices 2 a-2 n may be transferred to the cloud 204 via the network router 211 for data processing and manipulation. Data associated with the devices 2 a-2 m may also be transferred to the local computer system 210 for local data processing and manipulation.

It will be appreciated that the surgical data network 201 may be expanded by interconnecting multiple network hubs 207 and/or multiple network switches 209 with multiple network routers 211. The modular communication hub 203 may be contained in a modular control tower configured to receive multiple devices 1 a-1 n/2 a-2 m. The local computer system 210 also may be contained in a modular control tower. The modular communication hub 203 is connected to a display 212 to display images obtained by some of the devices 1 a-1 n/2 a-2 m, for example during surgical procedures. In various aspects, the devices 1 a-1 n/2 a-2 m may include, for example, various modules such as an imaging module 138 coupled to an endoscope, a generator module 140 coupled to an energy-based surgical device, a smoke evacuation module 126, a suction/irrigation module 128, a communication module 130, a processor module 132, a storage array 134, a surgical device coupled to a display, and/or a non-contact sensor module, among other modular devices that may be connected to the modular communication hub 203 of the surgical data network 201.

In one aspect, the surgical data network 201 may comprise a combination of network hub(s), network switch(es), and network router(s) connecting the devices 1 a-1 n/2 a-2 m to the cloud. Any one of or all of the devices 1 a-1 n/2 a-2 m coupled to the network hub or network switch may collect data in real time and transfer the data to cloud computers for data processing and manipulation. It will be appreciated that cloud computing relies on sharing computing resources rather than having local servers or personal devices to handle software applications. The word “cloud” may be used as a metaphor for “the Internet,” although the term is not limited as such. Accordingly, the term “cloud computing” may be used herein to refer to “a type of Internet-based computing,” where different services-such as servers, storage, and applications—are delivered to the modular communication hub 203 and/or computer system 210 located in the surgical theater (e.g., a fixed, mobile, temporary, or field operating room or space) and to devices connected to the modular communication hub 203 and/or computer system 210 through the Internet. The cloud infrastructure may be maintained by a cloud service provider. In this context, the cloud service provider may be the entity that coordinates the usage and control of the devices 1 a-1 n/2 a-2 m located in one or more operating theaters. The cloud computing services can perform a large number of calculations based on the data gathered by smart surgical instruments, robots, and other computerized devices located in the operating theater. The hub hardware enables multiple devices or connections to be connected to a computer that communicates with the cloud computing resources and storage.

Applying cloud computer data processing techniques on the data collected by the devices 1 a-1 n/2 a-2 m, the surgical data network can provide improved surgical outcomes, reduced costs, and improved patient satisfaction. At least some of the devices 1 a-1 n/2 a-2 m may be employed to view tissue states to assess leaks or perfusion of sealed tissue after a tissue sealing and cutting procedure. At least some of the devices 1 a-1 n/2 a-2 m may be employed to identify pathology, such as the effects of diseases, using the cloud-based computing to examine data including images of samples of body tissue for diagnostic purposes. This may include localization and margin confirmation of tissue and phenotypes. At least some of the devices 1 a-1 n/2 a-2 m may be employed to identify anatomical structures of the body using a variety of sensors integrated with imaging devices and techniques such as overlaying images captured by multiple imaging devices. The data gathered by the devices 1 a-1 n/2 a-2 m, including image data, may be transferred to the cloud 204 or the local computer system 210 or both for data processing and manipulation including image processing and manipulation. The data may be analyzed to improve surgical procedure outcomes by determining if further treatment, such as the application of endoscopic intervention, emerging technologies, a targeted radiation, targeted intervention, and precise robotics to tissue-specific sites and conditions, may be pursued. Such data analysis may further employ outcome analytics processing, and using standardized approaches may provide beneficial feedback to either confirm surgical treatments and the behavior of the surgeon or suggest modifications to surgical treatments and the behavior of the surgeon.

The operating theater devices 1 a-1 n may be connected to the modular communication hub 203 over a wired channel or a wireless channel depending on the configuration of the devices 1 a-1 n to a network hub. The network hub 207 may be implemented, in one aspect, as a local network broadcast device that works on the physical layer of the Open System Interconnection (OSI) model. The network hub may provide connectivity to the devices 1 a-1 n located in the same operating theater network. The network hub 207 may collect data in the form of packets and sends them to the router in half duplex mode. The network hub 207 may not store any media access control/Internet Protocol (MAC/IP) to transfer the device data. Only one of the devices 1 a-1 n can send data at a time through the network hub 207. The network hub 207 may not have routing tables or intelligence regarding where to send information and broadcasts all network data across each connection and to a remote server 213 (FIG. 4) over the cloud 204. The network hub 207 can detect basic network errors such as collisions, but having all information broadcast to multiple ports can be a security risk and cause bottlenecks.

The operating theater devices 2 a-2 m may be connected to a network switch 209 over a wired channel or a wireless channel. The network switch 209 works in the data link layer of the OSI model. The network switch 209 may be a multicast device for connecting the devices 2 a-2 m located in the same operating theater to the network. The network switch 209 may send data in the form of frames to the network router 211 and works in full duplex mode. Multiple devices 2 a-2 m can send data at the same time through the network switch 209. The network switch 209 stores and uses MAC addresses of the devices 2 a-2 m to transfer data.

The network hub 207 and/or the network switch 209 may be coupled to the network router 211 for connection to the cloud 204. The network router 211 works in the network layer of the OSI model. The network router 211 creates a route for transmitting data packets received from the network hub 207 and/or network switch 211 to cloud-based computer resources for further processing and manipulation of the data collected by any one of or all the devices 1 a-1 n/2 a-2 m. The network router 211 may be employed to connect two or more different networks located in different locations, such as, for example, different operating theaters of the same healthcare facility or different networks located in different operating theaters of different healthcare facilities. The network router 211 may send data in the form of packets to the cloud 204 and works in full duplex mode. Multiple devices can send data at the same time. The network router 211 uses IP addresses to transfer data.

In an example, the network hub 207 may be implemented as a USB hub, which allows multiple USB devices to be connected to a host computer. The USB hub may expand a single USB port into several tiers so that there are more ports available to connect devices to the host system computer. The network hub 207 may include wired or wireless capabilities to receive information over a wired channel or a wireless channel. In one aspect, a wireless USB short-range, high-bandwidth wireless radio communication protocol may be employed for communication between the devices 1 a-1 n and devices 2 a-2 m located in the operating theater.

In examples, the operating theater devices 1 a-1 n/2 a-2 m may communicate to the modular communication hub 203 via Bluetooth wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). The operating theater devices 1 a-1 n/2 a-2 m may communicate to the modular communication hub 203 via a number of wireless or wired communication standards or protocols, including but not limited to Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20, new radio (NR), long-term evolution (LTE), and Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, DECT, and Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. The computing module may include a plurality of communication modules. For instance, a first communication module may be dedicated to shorter-range wireless communications such as Wi-Fi and Bluetooth, and a second communication module may be dedicated to longer-range wireless communications such as GPS, EDGE, GPRS, CDMA, WiMAX, LTE, Ev-DO, and others.

The modular communication hub 203 may serve as a central connection for one or all of the operating theater devices 1 a-1 n/2 a-2 m and may handle a data type known as frames. Frames may carry the data generated by the devices 1 a-1 n/2 a-2 m. When a frame is received by the modular communication hub 203, it is amplified and transmitted to the network router 211, which transfers the data to the cloud computing resources by using a number of wireless or wired communication standards or protocols, as described herein.

The modular communication hub 203 can be used as a standalone device or be connected to compatible network hubs and network switches to form a larger network. The modular communication hub 203 can be generally easy to install, configure, and maintain, making it a good option for networking the operating theater devices 1 a-1 n/2 a-2 m.

The stage data 30070 may include a stage ID.

The stage may be further detailed by one or more sub-leaves, such as one or more surgical tasks 30076. The surgical task may represent a discrete surgical step within a given stage. For example, within the stage of access, placing a trocar may be a surgical task. The surgical task data 30076 may include a task ID. The surgical task data 30076 may include information related to the particular task, such as the staff and/or surgeon performing the task, the equipment to be used, the particular technique being applied, the patient vitals at the time the task is being performed, other environment information, and the list. Each task may be further detailed with goal data 30078, data related to an anatomy-instrument interaction 30080, and result data 30082. The goal data 30078 may include information indicative of the relative success of the task performance. The goal data 30078 may include information about expected task duration, acceptable performance specificity, efficiency modality, avoidance of complications, and the like. The result data 30082 may include information related to one or more goals. The result data 30082 may record the surgical performance (e.g., live and/or simulated) relative to the goals.

The task data 30076 may include one or more elements of anatomy-instrument interaction data 30080. The anatomy-instrument interaction data 30080 may represent a granular indication of surgical performance. The anatomy-instrument interaction data 30080 may represent the one or more specific activities used to perform the surgical task. The anatomy-instrument interaction data 30080 may represent the observable behavior of the surgeon.

In an example, the anatomy-instrument interaction data 30080 may include the specific positions, forces, angles, and the like being applied to the anatomy by the surgeon. For example in a live surgery, data recorded from smart instruments by the surgical hub 106 may be captured as anatomy-instrument interaction data 30080. For example, a smart surgical stapler in cooperation with other elements of the computer-implemented interactive surgical system 100 may record stapler position, angle, tip forces, jaw forces, staple cartridge type, closing pressure, firing rate, and the like. In a simulated surgery, similar data elements may be captured.

The contingency data 30072 may indicate any complications that may be relevant to the procedure. Each contingency data 30072 may include one or more task data elements 30084 that address the appropriate response to the particular complication. The contingency data 30072 may indicate deviations from an original procedure plan. Also for example, contingency data may be cross-referenced to one or more tasks 30078 and/or anatomy-instrument interactions 30080. For example, if a certain performance in an anatomy-instrument interactions 30080 could lead to a complication, the nature of that performance and a cross-reference to the contingency may include in the result data 30082 associated with that anatomy-instrument interactions 30080.

The result data 30074 may be indicative of the result of the procedure. Here overall metrics of the surgical performance may be stored, notes, actual and/or simulated patient recovery information, and/or patient outcomes. For example, the result data 30074 may include efficiency information, cost information, surgical duration, workload metrics, percentage of planned consumables used, and the like.

FIG. 11B illustrates a procedural plan data structure with the above disclosed elements, which further establishes structure of alternative steps for completing a particular procedure, task, or activity. As shown, the procedure represented by the procedure data 30086 may include two alternative setups, each indicated by respective setup data-a first setup data 30088, 30090 and a second setup data 30092. The first setup data 30088, 30090 may include two alternative tasks 30094, 30096. The second setup data 30092 may include one task 30098. In this illustration, the procedure represented by procedure data 30086 may be accomplished in three different ways. First via first setup 30088 and the first task 30094. Second via the first setup 30090 and the second task 30096. And third via the second setup 30092 and its corresponding task 30098.

Each path of the tree structure may represent a particular set of alternative ways to perform the procedure. Such a structure may be useful to aid the creation of a particular procedure plan for a particular live and/or simulated surgery. Such a structure may be useful to simulate many possible alternatives of a procedure to assess the differences in results.

Each of the plurality of simulations may be associated with a respective surgical setup. For example, the simulation may simulate activity in a surgical operating room associated with a respective surgical setup. The surgical setup may comprise a surgical equipment setup and/or a surgical staff setup. In examples, the surgical equipment setup may include one or more surgical equipment involved in performing a surgical procedure. For example, the surgical equipment setup may include a harmonic scalpel, a monopolar or bipolar radiofrequency (RF), a linear stapler, and/or a circular stapler if simulating a colorectal surgery. In examples, the surgical staff setup may include the surgical staff involved in performing a surgical procedure. For example, the surgical staff setup may include a primary surgeon, an assisting surgeon, a nurse, an anesthesiologist, and/or an assistant.

Information related to the surgical setup may be received from a surgical data system as described with respect to FIG. 7. The information may be indicative of the surgical procedure to be performed. The surgical data system may be a surgical hub associated with a medical facility. The surgical data system may store historical surgical setup data associated with real-life surgical procedures performed by the staff of the medical facility. For example, a medical facility may perform X number of colorectal surgeries. The surgical data system associated with the medical facility may store data associated with which medical instruments were used for the respective surgery. The surgical data system associated with the medical facility may store data associated with which medical staff were used for the respective surgery. The simulator may send a request message to the surgical data system requesting the stored data associated with the medical instrument and the stored data associated with the medical staff, for example, if the simulator is simulating a plurality of surgical setups related to a colorectal surgery.

At 32505, a plurality of performance scores may be generated. Each of the plurality of performance scores may correspond to a surgical setup simulated by the simulator.

Generating the performance scores may be based on surgical costs. The surgical costs may be associated with a surgical duration, a surgical movement, surgical complications, and/or patient outcomes. In examples, the surgical costs may be the duration of the surgical procedure. For example, a performance score of Z may be associated with a surgical procedure that took 90 minutes to complete. In examples, a performance score of T may be associated with a surgical procedure that took 150 minutes to complete. In such a case, the performance score of Z may be associated with a higher value than the performance score of T.

In examples, the surgical costs may include number of collisions. For example, a simulator may simulate performing a surgical task with L number of medical staff members on the left side of the patient and Q number of medical staff members on the right side. The simulator or one application module of the simulator as described with respect to FIG. 7 may count the number of times a medical staff member collided with another medical staff member as the surgical task is simulated. A collision may occur when the coordinate points of a medical staff member match the coordinate points of another medical staff member.

The surgical costs may include the accessibility of each medical staff member to the patient. For example, a simulator may simulate performing a surgical task with 4 medical staff members a S distance from the patient. The simulator may assess how many of the medical staff members are able to access the patient throughout the simulation of the surgical task. The simulator may access to what degree the medical staff member may access the patient.

The surgical costs may include the complication rate associated with the surgical procedure. For example, a performance score of Y may be associated with a surgical procedure with a complication rate of 5%. For example, a performance score of R may be associated with a surgical procedure with a complication rate of 1%. In examples, the performance score of R may be associated with a higher value than the performance score of Y.

Generating the performance scores may be based on a combination of surgical costs. In examples, the surgical costs may be weighted. For example, a surgical cost associated with a greater weight may have more of an impact on generating the performance score when compared to a surgical cost associated with a lesser weight.

At 32510, a first surgical setup may be determined. In examples, the first surgical step may be determined from the plurality of surgical setups based on performance scores associated with each of the plurality of surgical setup. In examples, a first surgical setup associated with a highest value performance score may be determined. For example, each of the plurality of surgical setups may be associated with a complication rate. The surgical setup with the lowest complication rate may be associated with a highest value performance score. In such a case, the surgical setup may be determined.

A scoring function may be received. In examples, the scoring function may be received from the surgical data system as described with respect to FIG. 7. The scoring function may be used to generate the plurality of performance scores. For example, values associated with each surgical setup may be inputted into the scoring function. The scoring function may generate performance score based on the inputted values. The values may be associated with the number of equipment, respective positions of equipment, and type of equipment as described herein. The values may be associated with the number of staff, respective positions of staff, and role of staff as described herein. The values may be associated with the surgical costs as described herein.

At 32515, a first surgical setup may be outputted. In examples, the first surgical setup determined from the plurality of surgical setups as described herein may be outputted.

In examples, the database may be included in the surgical data system as described with respect to FIG. 7. The information 32525 may be related to the surgical equipment setup and/or surgical staff setup as described with respect to FIG. 12. For example, the information 32525 may include the surgical setup used during patient X's surgical procedure and the patient's response to the surgical procedure. A response may be a complication that the patient experienced during and/or after the surgical procedure. For example, the database may indicate that for patient X, four surgical staff were involved in the surgical procedure and two harmonic scalpels were used in the surgical procedure. The database may indicate that patient X experienced internal bleeding after the surgical procedure. Information 32525 associated with surgical duration, surgical movement, surgical complications, and/or patient outcomes as described with respect to FIG. 11A may be recorded by the database.

Each of mobilizing the colon, resecting the colon, and anastomosis tasks may be simulated with a surgical setup of two harmonic scalpels and five surgical staff. Task impacts 32555 may be determined for mobilizing the colon, resecting the colon, and anastomosis, respectively.

A staff-equipment operating room interaction modeling 32550 may be used to determine the task impacts 32555. The staff-equipment operating room interaction modeling 32550 may be a module of the simulator. The staff-equipment room operating room interaction modeling may be a module of a remote computer.

Multiple pieces of equipment may be engaged and used to monitor the reactions of a first piece of equipment to the behavior or output from a second piece of equipment. A simulator may be used to assess the different equipment and/or devices used during surgery, for example, for evaluation and/or assessment prior to purchasing.

Utilizing a simulator may be used to evaluate and/or assess equipment and/or devices prior to purchasing, for example, which may give the facility an opportunity to determine the impact the equipment and/or devices may have to the OR environment and/or user interaction. The impact may indicate the benefit and/or value that the equipment and/or devices may add to the facility. Equipment and/or devices may be decided by individuals and/or facility that do not use the equipment. Decisions may be made based on a comparison of cost verses understanding overall impact to the facility. The simulator may be ran utilizing different equipment and/or devices to baseline against the current facilities setup, for example, to understand the overall impact to cost to the facility, e.g., the new equipment may cost less but the new equipment adds time to procedure which may cost more to the facility overall. The simulator may assess and/or compare errors to determine, for example, if the new equipment may cause more errors or downtime due to staff interface than current facilities setup.

Simulation may compare a first set of equipment and a second set of equipment with the same number of support staff to determine the differing combinations of instruments and or equipment that achieve better outcomes, timing, and/or efficiency than the first set of equipment.

In examples, the first set of equipment may be run through the automated simulation resulting in a baseline for behavior. The comparative set may be run through the automated simulation to identify inefficiencies and/or improvements.

The automated simulations may be used to identify the interdependencies of equipment with the need for increased staff to support the equipment. The automated simulations may be used with multiple adaptive runs to determine, for example, if the improved efficiencies of the equipment are durable.

The results of the equipment behavior under these simulated runs may be used to train personnel on what to expect, for example, when using the equipment and to teach the techniques and nuisances of the equipment to new personnel.

Simulation of differing numbers of support staff with a predefined set of equipment to determine the impacts of the equipment on personal needs may be provided. The behavior and required monitoring and/or interaction of the equipment may be simulated to determine the impacts of the new equipment on the support staff within the OR. The simulations may involve delays of the procedure, for example, as HCPs are interacting with the equipment. The simulations may result in lower staff needed to run all of the interrelated equipment.

FIG. 13 shows example comparison of simulated surgical setups.

A simulator 32520 may be provided. The simulator 32520 may be the core simulation module as described with respect to FIG. 7.

A surgical setup may be simulated. In examples, simulating the surgical setup may comprise the simulation simulating activity in a surgical operating room associated with the surgical setup as described with respect to FIG. 12. The surgical setup may be simulated via one or more modules. In examples, the modules may include the physics module, physiology module, metrics extraction module, and/or the interface module as described with respect to FIG. 7.

The simulate surgical setup module 32530 may be in communication with a database. The database may record information 32525 related to past surgical procedures. In examples, the database may be included in the surgical data system as described with respect to FIG. 7. The information 32525 may be related to the surgical equipment setup and/or surgical staff setup as described with respect to FIG. 12. For example, the information 32525 may include the surgical setup used during patient X's surgical procedure and the patient's response to the surgical procedure. A response may be a complication that the patient experienced during and/or after the surgical procedure. For example, the database may indicate that for patient X, four surgical staff were involved in the surgical procedure and two harmonic scalpels were used in the surgical procedure. The database may indicate that patient X experienced internal bleeding after the surgical procedure. Information 32525 associated with surgical duration, surgical movement, surgical complications, and/or patient outcomes as described with respect to FIG. 11A may be recorded by the database.

The simulate surgical setup module 32530 may request the information 32530 from the database, for example, if determining parameters for the surgical setup. For example, the parameters may include number of equipment, respective positions of equipment, and type of equipment as described with respect to FIG. 12. For example, the parameters may include number of staff, respective positions of staff, and role of staff as described with respect to FIG. 12.

The simulate surgical setup module 32530 may determine a baseline surgical setup. The baseline surgical setup may be a surgical setup with one or more optimal parameters for a given surgical procedure. The parameters may be optimal for a respective surgical cost. For example, the parameters may be optimal for surgical duration. In such a case, the parameters may be associated with a lowest surgical duration. For example, the parameters may be optimal for surgical complication rate. In such a case, the parameters may be associated with a lowest surgical complication rate.

The baseline surgical setup may be simulated by the simulator 32520 and the simulator 32520 may generate a baseline score. The baseline score may be a performance score as described with respect to FIG. 12. The baseline score may be based on the surgical costs described herein. For example, a surgical duration of X may be associated with a baseline score of 4. For example, a surgical complication rate of Y may be associated with a baseline score of 6.

The simulate surgical setup module 32530 may determine a comparative surgical setup. The comparative surgical setup may include a surgical setup with one or more potential parameters for a given surgical procedure. The potential parameters may be potentially optimal for a respective surgical cost. For example, the parameters may be potentially optimal for surgical duration. For example, the parameters may be potentially optimal for surgical complication rate.

The potential parameters may be different than the optimal parameters in terms of number of equipment, respective positions of equipment, and type of equipment. For example, the potential parameters may include two harmonic scalpels and the optimal parameters may include three harmonic scalpels. The potential parameters may include 30 total equipment. The optimal parameters may include 25 total equipment. In examples, the potential parameters may include a robotic arm located at coordinates x and y. The optimal parameters may include a robotic arm located at r and z.

The comparative surgical setup may be simulated by the simulator 32520 and the simulator 32520 may generate a comparative score. The comparative score may be a performance score as described with respect to FIG. 12. The comparative score may be based on the surgical costs described herein. For example, a surgical duration of L may be associated with a comparative score of 5. For example, a surgical complication rate of Q may be associated with a comparative score of 3.

The simulator 32520 may determine a surgical setup to output 32535 based on the baseline score and the comparative score. In examples, the simulator 32520 may compare the baseline score against the comparative score. In such a case, the simulator 32520 may determine which score is greater and choose the surgical setup associated with the higher score to output 32535. For example, the simulator 32520 may choose the baseline surgical setup to output 32535 if the baseline score is greater than the comparative score. In examples, the simulator 32520 may determine which score is lower and choose the surgical setup associated with the lower score to output 32535. For example, the simulator 32520 may choose the comparative score if the comparative score is lower than the baseline score.

FIG. 14 shows an example surgical setup simulator module.

One or more tasks 32545 may be associated with a surgical procedure. Each task 32545 may be simulated with a surgical setup, for example, to output a respective task impact 32555. For example, a colorectal surgery may include mobilizing the colon, resecting the colon, and anastomosis tasks. Each of mobilizing the colon, resecting the colon, and anastomosis tasks may be simulated with a surgical setup of two harmonic scalpels and five surgical staff. Task impacts 32555 may be determined for mobilizing the colon, resecting the colon, and anastomosis, respectively.

A staff-equipment operating room interaction modeling 32550 may be used to determine the task impacts 32555. The staff-equipment operating room interaction modeling 32550 may be a module of the simulator. The staff-equipment room operating room interaction modeling may be a module of a remote computer.

The staff-equipment operating room interaction modeling module 32550 may request data from a surgical hub. In examples, the surgical hub may be a surgical data system as described with respect to FIG. 7. The data requested may include staff data 32565, operating room data 32570, and/or equipment data 32575. The staff data 32565 may be data related to the surgical staff setup as described with respect to FIG. 12. The equipment data 32575 may be data related to the surgical equipment data as described with respect to FIG. 12. The operating room data 32570 may be data related to surgical operating room as described with respect to FIG. 12. The operating room data 32570 may include a mapping to a coordinate plane. The mapping may allow the positions of the surgical staff and the surgical equipment to be mapped.

Initial setup data 32540 may be initiated on the simulator. The initial setup data 32540 may include patient data 32560. The initial setup data 32540 may include staff data 32565, operating room data 32570, and/or equipment data 32575 described herein. The staff data 32565, operating room data 32570, and/or equipment data 32575 may be sent to a staff-equipment operating room interaction modeling 32550 as described herein. The patient data 32560 may be received by the simulator. In examples, the patient data 32560 may be sent by the surgical data system with respect to FIG. 7 to the simulator, for example, upon a request message from the simulator for the patient data 32560.

Appended setup data 32580 may be appended in the simulator. An appended setup data module may handle the appended setup data 32580. The appended setup data module may receive the tasks 32545 and task impacts 32555, for example, from the staff-equipment operating room interaction modeling 32550 described herein. The appended setup data module may include a staff-equipment operating room model 32585 that coordinates the tasks 32545 and task impact 32555. In examples, the staff-equipment operating room model 32585 may insert the task 32545 and tasks impacts 32555 in a list. The simulator may be able to assess the task impacts 32555 and determine a first surgical setup, as described with respect to FIG. 12 based on the tasks impacts 32555.

Simulation of patient variables and/or procedures for evaluation of attached equipment behavior may be provided. Automated simulation of patient parameters and/or surgeon tasks and reactions may determine the reaction utilized equipment and devices. Equipment used to perform procedure step may be supplied with a varying adaptive array of patient responses and surgeon interaction to identify and/or monitor the reactions of equipment to the varying condition. Multiple pieces of equipment may be engaged and used to monitor the reactions of a first piece of equipment to the behavior or output from a second piece of equipment. A simulator may be used to assess the different equipment and/or devices used during surgery, for example, for evaluation and/or assessment prior to purchasing.

Utilizing a simulator may be used to evaluate and/or assess equipment and/or devices prior to purchasing, for example, which may give the facility an opportunity to determine the impact the equipment and/or devices may have to the OR environment and/or user interaction. The impact may indicate the benefit and/or value that the equipment and/or devices may add to the facility. Equipment and/or devices may be decided by individuals and/or facility that do not use the equipment. Decisions may be made based on a comparison of cost verses understanding overall impact to the facility. The simulator may be ran utilizing different equipment and/or devices to baseline against the current facilities setup, for example, to understand the overall impact to cost to the facility, e.g., the new equipment may cost less but the new equipment adds time to procedure which may cost more to the facility overall. The simulator may assess and/or compare errors to determine, for example, if the new equipment may cause more errors or downtime due to staff interface than current facilities setup.

Simulation may compare a first set of equipment and a second set of equipment with the same number of support staff to determine the differing combinations of instruments and or equipment that achieve better outcomes, timing, and/or efficiency than the first set of equipment.

In examples, the first set of equipment may be run through the automated simulation resulting in a baseline for behavior. The comparative set may be run through the automated simulation to identify inefficiencies and/or improvements.

The automated simulations may be used to identify the interdependencies of equipment with the need for increased staff to support the equipment. The automated simulations may be used with multiple adaptive runs to determine, for example, if the improved efficiencies of the equipment are durable.

The results of the equipment behavior under these simulated runs may be used to train personnel on what to expect, for example, when using the equipment and to teach the techniques and nuisances of the equipment to new personnel.

Simulation of differing numbers of support staff with a predefined set of equipment to determine the impacts of the equipment on personal needs may be provided. The behavior and required monitoring and/or interaction of the equipment may be simulated to determine the impacts of the new equipment on the support staff within the OR. The simulations may involve delays of the procedure, for example, as HCPs are interacting with the equipment. The simulations may result in lower staff needed to run all of the interrelated equipment.
